An idea to make books more accessible to F2P since we have VERY LITTLE opportunity to get any still...Is have book pages, or chapters drop in certain areas such as dungeons. Say, you need 10 "rare chapters" for a full Rare book, You need 20 "epic chapters" for an epic spell book, and 50 "legendary chapters" for a legendary book.  I'm not saying do make these drop 40% of the time even like 5% for rare chapters 2.5% for epic and 1% for legendary or something. (rare chapters in the market). I feel this would make it more accessible to players and still requiring a grind.
